Specification of Letters Patent.

Patented Dec. 17, 1918.

Application filed April 19, 1916. Serial No. 92,143.

To all whom it may concern:

Be it known thatl, JOHN F. STANDISH, a citizen of the United States, residing at lVinthrop, in the county of Essex and State of Massachusetts, have invented certain Improvements in the Art of Heeling Shoes, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.

This invention relates to methods of attaching heels to boots and shoes and more particularly to methods of attaching heels comprising a leather and a rubber section. It is an object of the present invention to provide a method whereby the complete heel may be attached at a single operation, as distinguished from the methods heretofore practised in accordance with which the leather section and the rubber section have been-attached in successive operations by separate gangs of attaching nails. My co pending application Serial No. 53,948, filed October 4, 1915, discloses a machine intended for attaching such heels in that manner. By the method of the present invention I have succeeded in eliminating one of the nail driving operations heretofore necessary, thus reducing the expense of attaching heels of this class, and at the same time greatly simplifying the mechanism neces-' sary for attaching such heels. Moreover, the practice of my novel method improves the accuracy with which the heel sections are located upon the shoe and subjects the rubber section to less detrimental usage than formerly. The quality of the work and the condition of the rubber are therefore improved and the life of the heel lengthened.

In one of its aspects my novel method is characterized by first permanently securing together the rubber and leather sections of the heel and then attaching the heel so formed to the sole of the shoe to be heeled.

The manner of securing together the leather and rubber sections is not of particular moment. As herein shown they are cemented together while each section is held against angular displacement by a suitable.

holder. In this manner accurate location of the sections 1s secured and a permanent andsatisfactory bond is formed.

It is desirable in driving attaching nails into a rubber heel section neither to subject the rubber section to an excessive pressure nor to cut the material of the section by forcing drivers into it, as such treatment impairs-the shape and consistency of the rubber. novel method, the pressure necessary to insure a close union between the heel and the shoe sole is secured by pressure applied to the leather section while the rubber section remains substantially uncompressed.' As herein shown the desired results are secured by building a sectional heel having a shoulder formed by a portion of the leather section, pressing the heel against the shoe sole by pressure on this shoulder, and driving the attaching nails While the heel is so held.

Another characteristic step of the method of the present invention consists in holding the completed heel in predetermined relation to the drivers by a holder similar in Accordingly, in practising my shape to that used in holding the rubber secthis invention will be apparent from a consideration of the following description in connection with the accompanying drawings illustrating the preferred manner of practising the method, in which,

inwardly from the tread surface of the heel to the washers. A rubber heel section of this description constitutes the subject-inatter of my co-pending application Serial No. 3173, filed January 19, 1915, to which reference may be had for a detailed description thereof. Each conical Washer 10 serves to deflect into its opening the .point of an attaching nail, thus insuring the passage of the nail through the washer, while the Washer as a whole affords firm holding for the nail in the heel section when the head of the latter is driven to the surface of the washer. As indicated in Fig. 1 the first step of the method consists in coating the upper surface of the rubber section 8 with cement, as for example rubber cement 14. This may be applied by means f a brush 16 or in any other suitable manner.

The leather heel section 18 is shown in inverted position in Fig. 2. This section is of appreciably larger dimension than the rubber section and is intended to be reduced tothe desired ize by trimming after the, attaching operation. The second step of the present method consists 'in applying cement 14 to the outer surface of the leather Se"- tion. This may be done with the brush'18 as before.

The next-step of the method consists in permanently securing togetherthe leather section 18 and the rubber section 8 in that relation which they are to occupy in the This may be efiected by bringing the two cemented and partially dried surfaces. into engagement and pressing the surfaces together.

it is desirable that when the sections of the heel are first brought into contact they should occupy the desired relative positions for the nature of the cement renders it dithcult to vary or correct the relationship of the two sections after contact is made. in Fig. 3 there is shown one form of apparatus which may be employed to good advantage in carrying out this step. This apparatus comprises a bottom plate 20 having an aperture 22 shaped to receive one of the rubber sections 8. Preferably the plate is provided with a series of apertures of various sizes so that rubber sections of difierent sizes may.

' tained in position beneath the die plate. The

gin of a leather section 18 and hold it in the proper relation to the rubber section beneath it. When the illustrated apparatus is messes used the leather section is presented in the aperture 26 with its cemented face down. A permanent union is secured between the two sections of the heel by applying pressure to the heel seat surface of the leather section 18, the two sections being thereupon permanently united by the rubber cement. The" marginal portions of the leather section 18 will ordinarily be maintained out of contact with the upper surface of the plate 20 by the slightly thicker rubber section 8 but if such contact should occur no substantial bond will be established between the cemented surface of the leather section and the uncemented surface of the metal plate.

Having constructed the heel as above outlined it is removed from the heel building apparatus and is ready for attachment to the shoe sole. In this operation the leather section 18 i pressed against the sole of a shoe with sufficient force to insure a perfect union in the nail driving operation by pressure upon the marginal shoulder 19 formed at the base of the rubber section 8.

. washers 10.

Figs. 4 and 5 illustrate suflicient of the construction of a heel attaching machine suitable for carrying out the attaching step of the method to convey a clear understanding thereof. This machine is disclosed in full detail in United States Patent No.-

1,207,563, granted on an applicationof H. W. Kenway, to which reference may be had for features not herein illustrated. This machine is provided with astationary die plate 30 provided with nail receiving passages for the attaching nails and with a jack 32 upon which the shoe to be heeled is supported. Beneath the die plate 30 are provided ways for an apertured heel holding plate 34. The aperture in plate 34, as shown in Fig. 5, corresponds exactly in shape to the aperture 22 of the plate 20 in the heel building apparatus so that when a'completed heel is presented its rubber section 8 completely fills the aperture and the'heel is rethickness of the plate 34: is substantially equal to that of the rubber section 8 so that mented surface of the leather section 18.

The amount of premiere thus developed, however, is relatively slight and will not produce substantial deformation of the rubber section in any case.

The machine frame 36 is provided with vertical bearings for side rods 38 carrying a cross head 40 having a gang of drivers 42 mounted thereon and arranged in alinement with the nail receiving passages. The jack 32 is carried by a vertically movable jack carriage'44 resting on a block 46 and arranged to be elevated vertically by the action of a pair of cams 48 oscillated by the power of the machine during the initial movement of the cross head.

When the machine herein shown is employed for carrying out the present step of themethod, the heel is placed in the apertured holder plate 34 as shown in Fig. 5 and theshoe is placed upon the jack 32 with its sole 28 uppermost. The jack is then elevated into preliminary engagement with the heel seat surface of the leather section 18 of the heel and the machine thereupon started. The cams 48 then act to-elevate the'jack: and the leather section 18 is firmly pressed, by pressure upon its marginal portion, against the shoe sole. While the leather section 18 is so held under pressure and the rubber section remains substantially uncompressed, the cross head 40 continues to descend and the attaching nails 11 are driven downwardly from the nail receiving passages in the die plate 30, being followed by the drivers until their heads are seated upon the upper surfaces of the washers 10. The attaching nails pass through the sole 28 and are clenched inside the shoe thus attaching the completed heel firmly in place. The cross head is then lifted and the jack lowered with the heeled shoe, drawing the rubber section 8 out of the aperture in the plate 3% and leaving the machine in readiness for operating upon the next shoe. 7

It will be apparent that the machine herein described is in no way essential to the practice of the method of my invention, but that any heel attaching machine, equipped to hold the heel in the manner above outlined and to drive the attaching nails while the heel is so held, might equally well be employed.

Having thus described my novel method and preferred apparatus for carrying it into effect, what I claim and desire to secure by Letters Patent of the United States is:
